Technical Exchange with Japan
We actively conduct technical exchanges with “AEROV,” Yamaichi Special Steel’s precision machining plant in Japan, and share machining know-how cultivated in Japan to enhance our technological capabilities.
As a result, since the establishment of YSV in 2012, we have built a proven track record of supplying to many major customers, including Tier-1 class suppliers of leading Japanese automobile manufacturers.


Temperature Control
Metal materials expand and contract with temperature, which can cause variations in dimensional accuracy depending not only on the season but even on the day’s temperature.
In YSV’s finishing machining room, temperature is controlled and recorded throughout the year at 24℃ ±1℃ to ensure higher accuracy.
Examples of machining accuracy:
Pitch accuracy ±0.005 (wire-cut machining accuracy)
2D shape tolerance ±0.005 (wire-cut machining accuracy)
3D shape tolerance ±0.02 (products machinable with F3)
3D shape tolerance ±0.01 (products machinable with YMC430)
Introduction of Japanese-Made Equipment
We are fully equipped with essential finishing machinery, including 3-axis machining centers, CNC lathes, grinders, and wire EDM.
All equipment is manufactured in Japan, contributing significantly to high precision.
We can handle products up to W400 x L500 for full machining.
For larger sizes, please consult us for availability.
